Let's first understand the characteristics of the household solar photovoltaic power generation and energy storage all-in-one machine.
1. Smart mode switching, easy and safe to use
Household solar photovoltaic power generation and energy storage all-in-one machine is an integrated integrated system that puts photovoltaic inverter, battery and controller inside. It can display the working status conveniently, quickly and intuitively through the touch screen, and can modify parameters and multiple working modes for easy use.
Generally, there are three working modes: solar energy priority mode; AC (mains power) priority mode; SE priority mode (peak staggered power consumption mode).
Some advanced products are already relatively intelligent, which can realize multi-source power supply of photovoltaic and mains power, and intelligently switch between power storage and power generation modes according to user scenarios.
Better products basically use lithium iron phosphate batteries, which have the characteristics of high safety and long cycle life, and the products are more secure.
2. Save electricity costs, save energy for backup
Today, under the influence of energy crisis + extreme weather, the cost of electricity consumption of residents has been rising year by year, and power outages are often required, and the stability of power supply is relatively poor. Everyone's life has been significantly affected.
According to the working principle of household solar photovoltaic power generation and energy storage all-in-one machine, basically in the case of 24-hour electricity supply for the home, there may be surplus electricity turned over to the national grid for income. Regardless of subsidies, the rate of return can reach more than 15%, which can be regarded as a high-yield, short-payback household electricity investment project.
